US President Donald Trump has repeated calls for the suspect in the New York truck attack to get the death penalty.

But Mr Trump backed away from his call a day earlier to send Sayfullo Saipov to Guantanamo Bay, saying "that process takes much longer".

The suspect, who allegedly drove along a Manhattan cycle path killing eight people, told police he "felt good" about Tuesday's Halloween attack.

Later, so-called Islamic State (IS) said it had carried out the attack.

The attacker was "one of the caliphate soldiers", it said in its weekly al-Naba newspaper, without providing evidence to support the claim.
